Abstract
The invention discloses a production process of medical antibacterial fabric, which relates to the technical field of antibacterial fabric, is a mixed fabric formed by mixing and spinning the following fibers in parts by weight, and comprises 10-20 parts of polyester fibers, 10-20 parts of viscose fibers and 10-20 parts of superfine fibers, wherein the mixed fabric is formed by carrying out antibacterial agent padding treatment on the mixed fabric, and specifically comprises the following steps: s1, one-bath dyeing: putting 10-20 parts of polyester fiber, 10-20 parts of viscose fiber and 10-20 parts of superfine fiber into the same container, adding 1-3% of an antibacterial agent and adding a dye according to requirements, S2, padding: mixing and spinning 10-20 parts of polyester fiber, 10-20 parts of viscose fiber and 10-20 parts of superfine fiber by a spinning machine, adding an antibacterial agent, padding, and keeping the mangle ratio at 70-90%; according to the invention, the graphene is of a hydrophobic plane structure and a hydrophilic edge structure, and microorganisms stimulate free radical reaction through charge transfer after contacting the graphene material in the fabric, so that the cell membrane structure of the microorganisms is destroyed and the microorganisms die.
Description
Technical Field
The invention relates to the technical field of antibacterial fabrics, in particular to a production process of a medical antibacterial fabric.
Background
With the continuous development of scientific and technological technology and the continuous improvement of living standard of people, people gradually pursue comfortable and antibacterial fabrics, and in textile fabrics, because the fabrics belong to the chemical structure of high molecular polymers and the shape of porous objects, microorganisms have good habitats for survival and reproduction and attachment, but the microorganisms not only have harm to human bodies and pollute fiber fabrics, but also cannot be used in the medical field, so the antibacterial fabrics are widely concerned by people in the medical field.
The antibacterial fabric is a textile fabric consisting of fibers, the antibacterial fabric injection agent is fixed inside the nylon fibers and the polyester fibers at high temperature so as to protect the fibers from easily generating microorganisms, and the reason for the antibacterial fabric injection agent for resisting bacteria is that the osmotic pressure inside microbial cells is 20-30 times of the osmotic pressure outside the microbial cells, so that the microbial cells are broken to stop the metabolism of the microbial cells, thereby achieving the effects of sterilization, bacteriostasis and antibiosis.
The metal ions are added into the existing antibacterial fabric to achieve the antibacterial characteristic, so that the fabric has good heat resistance and durability besides the antibacterial effect, but the metal ions have the defects of large using area, easy color change and high cost, so that the metal ion antibacterial fabric cannot be widely used, and in addition, a natural antibacterial agent is added into the fabric, is extracted from natural plants such as chitin, mustard, castor oil, horseradish and the like, but has limited antibacterial capability and poor heat resistance, so that the using amount is small.
